Universal switch airspeed
kit (USW-1) includes an ASW-1 airspeed switch and a Universal
Switch-SPDT controller. This combination of components allows for the
switching of electrical loads up to 10 amps and up to 30 volts based on aircraft
speed. The airspeed set point is factory calibrated to 100 knots, however, it
may be field adjusted to switch at any speed between 55 and140 knots. The
Universal Switch-SPDT controller provides both a normally open and a normally
closed contact for controlling any electrical load up to 10 amps. This allows
electrical loads to either be on or off, above or below the airspeed set
point. The system works with aircraft power systems from 10-30 volts.
